Seems that any program that has a default data directory, or previously
selected directory preserved, has the directory duplicated/nested:
That data is in c:\mystuff\mydata
It is shown as c:\mystuff\mydata\mydata
The files appear and maybe can be read. Any attempt to write produces an error
(obviously, there is no such directory). Some programs will crash/abort wine
trying to navigate this stuff.
This is a problem in recent wine (running Debian Sid). Programs ran correctly
before. Bug?
